This invention relates to welting and more the requisite finished appearance in the comparticularly to the manufacture of two-unit pleted shoe is obtained without the necessity welting known to the trade by the general of incorporating a third element such as a designation cork-sole or simply calk covering strip for the top unit.

The sequence and nature 'of the cutting steps in producing the strips 10 from the leather piece 16 is immaterial pro-- vided the described triangular top unit strip is eventually obtained.

The top-unit 10 is laid along the inner margin of the bottom unit 12 (see Fig. 3) with its widest face 2% against the grain of the bottom unit and with its grain side face 18 facing outward. This position causes the flesh side face 22 to lie against the shoe upper 26 (see Fi l) when the welting is stitched to the shoe, and the soft, spongy nature of the flesh enables the calking strip 10 to yield and conform toall inequalities of the welt crease and thus to hug the upper throughout its top edge.

Preferably the top unit or call: 10 is secured to the bottom unit by a dry thread seam 28 which is hidden from view in the completed shoe. To provide a smooth face 22 to lie against the upper the seam 28 is sunk into or buried in the surface, i. e. fudge-stitched, and to this end the face 22 is slit longitudinally as at 30. Preferably the plane of the seam 28 is such that it lies outside the inseam 32 (Fig. 4).

The novel welting may be secured to the insole 34 and outsole 36 of the shoe by usual methods.

\Vhen builtinto the shoe the welting presents a grain shoulder 18 in the welt crease comparable in finish to the adjacent grain 13 of the welt strand 12, and the upper edgeof the calk 10, or angle between its side faces 18 and 22, is conformed tightly and neatly to the upper, all without, the use of any material other than welting leather. Either of the flesh faces 22 or 24 may be laid against the upper to vary the style of the trim in the welt crease.

The nature and scope of the invention having been indicated and its preferred embodiment and method of manufacture having been specifically described, what is claimed as new,

.of a bottom unit substantially rectangular in cross-section having a grain face and a topnnit'triangular in cross-section having one -unit being secured to the grain face of the ottom unit with its grain face facing outward. 2. All-leather welting consisting of two units, one being a strand of grain Goodyear welting and the other being a strip of righttriangular cross-section out from welting leather in a manner to preserve the grain on.

one of the side faces of the strip, said two units being assembled with the strip lying with its hypothenuse face against the grain of the strand along the inner margin thereof and with its grain side face facing outward.

3. All-leather welting consisting of top and bottom units, the top unit thereof comprising a strip of triangular cross-section having one grain face and two flesh faces lying at the face in engagement therewith and its grain face forming an outwardly facing shoulder, and fastemngs-along the inner flesh face of nner margin of the bottom unit with one flesh 7 said strip passing from one unit into the other for securing them together. I 4. All-leather welting consisting offtop and bottom units, the-top unit thereof comfrom the flesh, and one flesh face havinga longitudinal slit therein to receive and pry. a seam for securing the two units together. 7

6. The method of making all-leather twounit welting which includes the steps of preparing a bottom unit strand of substantially rectangular cross-section from grain leather, preparing a top unit strip of triangular crossseetion by severing a strip of quadrilateral cross-section from grain leather and then dividing said strip on a diagonal, discarding the portion that has no grain face, then securing the triangular grain face strip to said strand in position to form an outwardly facing grain shoulder.

7 A welt shoe having an insole, an upper and a cork-sole welt secured thereto, the bottom unit of said cork-sole welt consisting of a strand of grain Goodyear welting and the top -unit consisting of a strip of triangular cross-section having one grain face and lying in the crease of the shoe with its grain face exposed and forming a continuationofthe grain. face of said bottom unit, said topiand bottom units being secured together b'ylceii cealed fastening means, and an outsole se cured to the bottom unit of said cork-sole welt.
